The time to failure (in hours) of fans in a personal computer can be modeled by an exponential distribution with l=0.0003
Dvinal [7]

Answer: 0.0497870 ; 0.87754

Step-by-step explanation:

Given that :

λ = 0.0003

Defining a continuous distribution function :

F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0

a. What proportion of the fans will last at least 10,000 hours?

P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870

b. What proportion of the fans will last at most 7000 hours?

P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)

1 - 0.12245642825 = 0.87754

A street has parallel curbs 40 feet apart. A crosswalk bounded by two parallel stripes crosses the street at an angle. The lengt
andreev551 [17]

Answer:

The distance, in feet, between the strip = 12 feet.

Step-by-step explanation:

From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where

CD/AB = CE/AE

CD = 40

CE = 50

AE = 15

Let AB = x

50x = 15 × 40

X = 12

 The distance, in feet, between the strip is therefore 12 feet

Solve the following equation. x/3 - 4 = 10
erma4kov [3.2K]

Answer: x=42


Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Solve for x.

- Add 10 and 4.

- Multiply the sum of 10 and 4 by 3. You must move it from the left member to the right member. Then, if  3 is dividing x, this will multiply the sum of 10 and 4. So, you have:

x/3=10+4\\x/3=14\\x=42

Therefore, you obtain that the value of x is 42

the radius of a circle is 10 using pi which equation expresses the ratio of the circumference of the circle to the circle's diam
grigory [225]

Answer:

pi

Step-by-step explanation:

The radius of the circle is 10 units

The circumference of a circle is given by the formula:

  C = 2 * pi * r

The diameter of a circle is twice the radius

d= 2r

We want the ratio of the circumference to the diameter

C/d  = (2*pi*r)/ 2r  

Canceling out the 2 and the r, we are left with pi

C/d = pi
